摘要： A weight detector for detecting the weight of a passenger seated on a vehicle seat includes a first load sensor and a second load sensor provided on opposite sides of a rear portion of the vehicle seat. Each of the first and second load sensors has a predetermined detection range. The weight detector further includes a third load sensor and a fourth load sensor provided on opposite sides of a front portion of the vehicle seat. Each of the third and fourth load sensors has a predetermined detection range. If a detection value based on a load acquired by one of the first through fourth load sensors exceeds its detection range, the weight detector uses an old value that was determined under proper condition. Otherwise, the weight detector determines the size of the passenger based on the currently detected values.

摘要： In a passenger weight measuring apparatus, each of bend parts of front and rear brackets for supporting a seat to a vehicle main body side becomes bent and deformed in response to the load applied by the weight of the passenger sit in the seat. A load sensor on each the bend part detects the load based on the bend deformation and outputs a voltage signal of magnitude responsive to the load to a signal processor. The processor generates a load detection signal clamped in the voltage range corresponding to a preset passenger weight load range from the voltage signal and outputs the load detection signal to an output terminal. When the detected load is a collision load set in a load region out of the load range, the processor outputs an abnormal load detection signal different from the load detection signal to the same output terminal.

摘要： A seating load detecting device in which a lower arm for supporting a seat cushion and a seat back is coupled with an upper rail by a front bracket and a rear bracket. A distortion gage is attached to the bracket. The bracket comprises a curved portion of a U-shape or V-shape. The lower arm and the upper rail are coupled to each other with the direction orthogonal to two opposing legs of the curved portion being vertical. The distortion gage has a total of four distortion detecting elements G11 to G22 distributed in a matrix distribution, two attached in the front and back directional plane of the legs and two attached in the width directional plane of the legs. Due to the Wheatstone bridge connection line of these elements, high gain of a seating load detection voltage e with respect to the amount in change of the vertical load Fv can be obtained.
